First track pass since mods
2012 base. Got BTR stage 1V2, full exhaust with NPP and off-road mid, rod mod intake, drag radials (275-40-18 Nitto R555-2) and Yank ss3600 converter.
made 3 passes, only 1 didn’t blow tires off on the hit. Good pass was leaving on idle with 22 lbs in the drag radials. They only had 1/8 mile clocks working.
Ran 7.17 @102 with 1.72 60’ feel there’s a high ten at least in there. 7.17 is equivalent to 11.28 according to the web page I accessed. I’m happy but want more. Did average 29 mpg there and back (85 miles each way)

Drop the pressure to 18#, do a solid 5 sec 2nd gear burnout and then launch around 1200-1500. Should hit 10's then.

congrats thats great 1st time results you should keep logging and trying different launch RPMs off idle then 2k then 2200 then 2500 but like HOXXOH said drop tire pressure first try 20psi then 18psi if you get stuck at 7.0 take out the passenger seat for that elusive 6.99999999999 lol

I agree with HOXXOH on tire pressure and a solid burnout. Might try different launch techniques though. I know when I had a motor car with the yank ss3600, the more I stalled it up, the harder it left. It did not like being flashed. I went bottom 1.5s on the regular with just bolt-ons and 19" radials. Try it at 1500, then at 2000, then 2500, then 3000, etc. I think I could footbrake mine up to 3200 or so if my memory is right.

With my 3600 and 275 x 17 Hoosiers, my best 60's were had with about a 1400-1500 launch. After switching to a 4000, my best times were with a 1700-1800 launch in the high 1.4's. That was with just bolt-ons. So going to internal mods, you'd need to find your own sweet spot. Nothing is set in stone, so everyone has to experiment with what they have, the track conditions at the time, and their technique. Just because everything worked well in the morning time trials, doesn't mean the mid-afternoon conditions will produce the same results.
